6v claims; (c1. iss-'57) This invention .relates to improvements indoors, and particularlyy .to rolling doors Vsupported so that the .doormaybe moved to and froma doorway in axwall.v l

It; is` also. an robject ofthis invention to pro.; vide a vdoor witlranopening: therein, and a closure for the opening, said door and closurebeing independently' supported and operated.l

It is ,Y also an object of this invention to. provide a rolling doorsupported by means of a drum for moving the door to and from a doorwayina wall. This ldoor 'is provided with an openingandna closure forclosing the opening, said closure being supported for movement withrelation to the door and operated. simultaneouslyl with .but independ#ent of the door.

)Theseand other advantages will; appearirom they followingdes'criptiontaken in connection with thedrawings.. v f Referring. to the drawings:

Figure 1 is a front elevation of the door, showing its supporting and.operating mechanism and the .guard therefonwith `the guardA and vthedoor partly vbroken away.` 1

`Figure 2 is a side elevation of the door and the closure supporting anoperating mechanism.

' Figure 3 is a section on the line. 3-3 of Figure 1.

Figure 4 is a section similar to Figure 3, showing the door-and theclosure in elevated positions.

Figure 5 is a section on the line V5--5 of Figure 3. f The present doorVis adapted to be used in connection with variousftypesV of buildingsiorclosing doorways therein. The. numerallI indicates the wall of abuilding, such as a garage, warehouse or zotherlbuilding. .In this wallis a doorway 2 adapted to be closed by the door, the subject-matter ofthis application.

On each side of the doorway and supported by the wall is an angle iron3, which has one arm suitably attached to the wall, while the other arm`projects from the wall at right angles thereto. Spaced from the angleiron 3 is an angle iron 4, which has one arm attached to the wall andthe other arm extending from the wall parallel to an arm of the angleiron 3. (Figure 5.)

Between these two angle irons is a space 5, into which projects one armof an angle iron 6, one arm of an angle iron 'l and a spacer block 8,which holds the angle irons 6 and 1 in a fixed position between theangle irons 3 and 4. The other arms of the angle irons 6 and 'I form agroove or space 9, in which one end ofthe door composed of sections I0ts and is guided.

The door sections have their opposite edges II looped with adjacentedges, interengaging for the purpose' of 4supporting the sectionsinhinged-relationship `with one another. The upper edge of the door issupported by lmeans of a drum I2, which may be rotated for elevatingor'lowering the door as the caseimay be. This drum is supportedjby meansof brackets I3, one at each end of therdru'm, supported -bylthe wall. Onthe lower edge of the door for engagement with the ,oor of.. theVbuilding to which the door is applied, an angle iron strip- I4 ,isattached. (Figures 1 and 3;)

The doorlfis provided with one or more openings'IE. At each endf of eachopening the door is strengthened bymeans of -a strapl. On each end. ofthe drum isa shaft Il, which serves to support the-.drumin bearingsprovided thereforinjthebracketsi'l3. On oner shaft Il 'is a gear I8,whichmeshes with a gear ,20, located on a shortyshaft I9 also supportedby one of the brackets I3.

' On lthis shaft` I9 is a sprocket' Wheel '2i over which-passesrasprocket chain 22 for rotating the gearI I8y and the drum I2.v There isalso provided on" the :bracket I3 a guide 23 for the sprocket chain.`The'openings in the door are closed by means of panelsconsistng of aframe 24, with panes of glass 25 therein.

z As shown iii-Figure ll ,thelclosure is in a position to closetheopenings in the door, and is sup- .portedin position by means'oi chainsor cables 26. Each `chain" or cable isy attached at one end to the loweredge ofthe closure,` while its vupper end isattached toa drum 2l locatedon one end iofnazshaft .28 supported by means of abracket 28u, supportedon a guardll'L y A On one end of the shaft '28 is a pinion 29, whichmeshes with the gear I8 so that as the door is operated to close or openthe doorway the panel is operated to open or close the opening in thedoor. The guard 30 is attached to the wall above the doorway and servesto pro# tect the drums and the shaft 28 from dust and other foreignmaterials.

The channelways 3I, which guide the ends of the closure, continueupwardlyk above the doorway and form housings 32, in which the ends of ythe closure rest when the door is open. These housings are at the backof and. above the guard 30, the guard having an upwardly extending part33 connecting the two housings so there is formed a complete closure forthe panels containing panes of glass.

In Figure 1 the door is shown in a closed position. In order to open thedoor the sprocket chain is operated so that the drum rotates to wind upthe articulated door. At the same time the shaft 2B and the drums arerotated so that the closure is moved with relation to the door. Thisclosure is moved vertically upwardly so that it will be housed behindand above the drum on which the door is rolled.

When it is desired to close the door the sprocket chain is operated inthe reverse direction, lowering the door and at the same time loweringthe panel which closes the opening in the door. On account of the pinion29 being smaller in diameter than the gear I8 the closure moves at agreater rate ofspeed than the door, and during the opening and closing`of the door moves at a speed different from that at which the door ismoved.' The closure is sup'- ported and operated independent of thedoor, the connection between the ktwo being the gear i8 and the pinion29, and the common actuating mechanism.

I vary the speed by' varying the spool size of 21 and thereby adjust theexact location of the closure 24, depending upon the height of theopening it is to close.

It will be understood that I desire to comprehend within my inventionsuch modifications as come Within the scope of my claims and myinvention. i v

Having thus fully described my invention, what I claim as new and'desire tosecure by Letters Patent, is:

l. In a door structure, a door composed of articulated sections andhaving therein an opening, a light transmitting closure for the opening,means to support and elevate the closure, means to support and roll upthe door, and operativelyinterconnecting means to operate both of saidmeans in timed relationship at the same time substantially throughoutthe period of closure of the door.

2. In a door structure,` a door` composed of articulated sections andhaving therein an opening, a light-transmitting closure for the opening,means to support and elevate the closure, means to support and, roll upthe door, andoperatively-interconnecting means to operate both of saidmeans in timed relationship. at the same time substantially throughoutthe period of closure of the door kat relatively different speeds.

3. In a door structure, a door composed of articulated sections andhaving therein an opening, a light-transmitting closure for the opening,means td support and elevate :the closure, means to support and roll upthe door, and operatively-intereonnecting means to operate both of saidmeans in timed relationship at the same time substantially throughoutthe period of closure of the door, said interconnecting means comprisinggearing operatively joining said closure-elevating means and saiddoor-supporting means.
